I'm a happy Firefox user on my PC and sometimes on my Mac, but browser market dynamics don't seem to be as advanced on mobile devices as they are on traditional PCs today. Users tend to use the native smartphone browser an order of magnitude more than they use the native browser on a PC, laptop, or netbook. If this trend continues, the leading mobile browser will be the browser shipped natively on the leading smartphone, with little room for a third-party browser to assert itself as a challenger or leader.

Firefox is being shipped as the native browser on two of Nokia's high end N-series smartphones built off the Maemo platform. But the rest of Nokia's smartphones are built off the Symbian platform. Additionally, Nokia's success in the smartphone market is not a fait accompli, as the iPhone, BlackBerry, and Android are viewed to be growing at Nokia and Symbian's expense.

Mobile Firefox clearly faces an uphill battle for inclusion as the native browser on leading smartphones. However, I wouldn't write Firefox off in the smartphone arena just yet.
